Description

Technical Field

[0001] This utility model relates to the field of titanium anode processing and manufacturing technology, and in particular to a titanium anode acid washing device. Background Technology

[0002] Titanium anodes, also known as titanium-based metal oxide coated titanium anodes, use titanium as a substrate and coat it with a precious metal coating. This gives them excellent electrocatalytic activity and conductivity. As a substitute material, titanium anodes are widely used in numerous industries such as chemical engineering, environmental protection, electroplating, water electrolysis, water treatment, electrometallurgy, electrodialysis, organic electrosynthesis, and cathodic protection. Currently, during the pickling process of titanium anode plates, they are manually placed into the pickling tank one by one. This results in multiple titanium anode plates not being placed into the pickling tank at the same time, creating a time difference and increasing pickling time. Therefore, a titanium anode pickling device needs to be developed. Utility Model Content

A drain pipe 3, communicating with the interior of the pickling cylinder 1, is fixedly installed on the peripheral wall of the pickling cylinder 1 near its lower end. An on / off valve 4 is provided on the drain pipe 3. By opening the on / off valve 4 on the drain pipe 3, the old acid solution inside the pickling cylinder 1 can be periodically discharged.

[0019] A vertical first rotating shaft 5 is rotatably mounted in the center of the bottom plate of the pickling tank 1. Multiple first stirring blades 6 are fixedly mounted on the first rotating shaft 5 at even intervals. A motor 7 for driving the first rotating shaft 5 to rotate is installed below the bottom plate of the pickling tank 1. Multiple second rotating shafts 8 are rotatably mounted circumferentially near the inner circumferential wall of the bottom plate of the pickling tank 1. Multiple second stirring blades 9 are fixedly mounted on each second rotating shaft 8 at even intervals. A drive gear 10 is mounted on the first rotating shaft 5 near the bottom plate of the pickling tank 1, and a driven gear 11 adapted to the drive gear 10 is mounted on each of the second rotating shafts 8.

[0020] The pickling drum 1 has an open upper end, and two horizontal mounting plates 12 are symmetrically fixed on its outer peripheral wall. An inverted U-shaped mounting bracket 13 is fixedly mounted on both mounting plates 12. A winch 14 is installed at both ends of the upper part of the mounting bracket 13, and the winch cables 15 of the two winches 14 are fixedly connected to a placement bracket that can enter the interior of the pickling drum 1 for placing titanium anode plates.

[0021] In this embodiment, the placement rack includes a lower inner ring 16. The outer peripheral wall of the lower inner ring 16 is fixedly connected to one end of a plurality of transverse connecting rods 17 evenly arranged along its circumference, and the other end of the plurality of transverse connecting rods 17 is fixedly connected to the inner peripheral wall of a lower outer ring 18. The lower inner ring 16 is located outside the circumference formed by a plurality of first stirring blades 6, and the lower outer ring 18 is located inside the circumference formed by a plurality of sets of second stirring blades 9. The upper part of the lower inner ring 16 is fixedly connected to one end of a plurality of vertical inner connecting rods 19 evenly arranged along its circumference, and the other end of the plurality of vertical inner connecting rods 19 is fixedly connected to the bottom of an upper inner ring 20. The upper part of the lower outer ring 18 is fixedly connected to one end of a plurality of vertical outer connecting rods 21 evenly arranged along its circumference, and the other end of the plurality of vertical outer connecting rods 21 is fixedly connected to the bottom of an upper outer ring 22. Each of the vertical inner connecting rods 19 and the plurality of vertical outer connecting rods 21 are respectively arranged in a one-to-one correspondence with the plurality of horizontal connecting rods 17. Each of the horizontal connecting rods 17 is fixedly provided with a bottom bracket 23 at its upper part, each of the vertical inner connecting rods 19 is provided with an inner bracket 24 on its outer side, and each of the vertical outer connecting rods 21 is provided with an outer bracket 25 on its inner side.

[0022] Two vertical connecting plates 26 are symmetrically fixed on the outer peripheral wall of the upper outer ring 22. Each connecting plate 26 has a lifting ring 27 fixedly installed on its upper part. The free ends of the winch cables 15 of the two winches 14 are respectively fixedly connected to the two lifting rings 27.

The bottom bracket, inner bracket, and outer bracket respectively limit and fix the bottom edge and two sides of the titanium anode plate. Then, the placement frame containing the titanium anode plate is moved into the pickling drum by a winch. The drive motor drives the first rotating shaft to rotate, and the meshing action of the driving gear on the first rotating shaft and the driven gears on each of the second rotating shafts causes the second rotating shafts to rotate synchronously. The rotating multiple first stirring blades and each set of second stirring blades stir the acid solution inside the pickling drum, thereby ensuring full contact between the acid solution and the titanium anode plate, effectively improving the pickling efficiency and ensuring the pickling effect. After the pickling operation is completed, the two winches lift the placement frame from the pickling drum by winding the winch cable. After the acid solution is drained, the pickled titanium anode plate can be removed from the placement frame.

[0025] Furthermore, as a further improvement to this utility model, a vertical drive cylinder 30 is fixedly installed in the upper middle part of the mounting frame 13, and the telescopic end of the drive cylinder 30 is fixedly connected to the pressure plate 31. When the placement frame is submerged inside the pickling tank, the drive cylinder extends, causing the pressure plate to move downward. Under the downward pressure of the pressure plate, the titanium anode plate in the pickling tank can be prevented from floating due to the buoyancy of the pickling solution.
